INVENTOR 1011 1 Jordan i United StatesPatent O 2,775,372 PROTECTIVE COVER FOR DISPENSING CONTAINERS Jack P.'Jordan, Roslyn, N. Y., assignor, by mesne assignments, to Crown Cork & Seal Company, Inc., Baltimore, Md., a corporation of New York Application August 6, 1953, Serial o. 372,703 I 2 Claims. (Cl. 2zz 1s2 My invention generally relates to an improved protective cover or cap for containers and more specifically to a protective cover or cap tor containers of the type employed for dispensing liquids, powders and the like by gas retained under pressure.

Therefore, it is an object of my invention to provide an improved protective cover or cap of the type described tor use with pressurized containers having reduced neck portions whereby the cover and container when assembled form substantially a cylindrical article which may be easily packaged for safe transportation and storage.

Another object of my invention is to provide a protective cover or cap which may be easily and quickly applied and removed from a container and which will remain firmly in place in position on the container when In use.

A still further object of my invention is to provide a novel cover or cap of the type herein described that may be formed from a plastic material by a single inexpensive molding operation and which is easily maintained in a clean, sanitary and hygienic condition.

The above and other advantages of my invention will become apparent from the following description and the accompanying drawing in which I have illustrated the protective cover of my invention associated with a conventional pressure type dispensing container. Throughout the description reference will bemade to the drawing wherein like characters denote corresponding parts throughout the several views, and in which:

Figure 1 is a side elevational of a container and the protective cover or cap of my invention in assembled relation.

Figure 2 is a sectional view of the embodiment of (Figurel.

Figure '3 is a sectional view of my protective cover or cap along the line 3-3 of Figure 1.

Figure 4 is an enlarged side elevation in section of the protective cover or cap of my invention, and

Figure 5 is a perspective view of the embodiment of Figure '1 in which parts of the protective cover or cap are shown broken away to more clearly illustrate the assembled relationship of the cover and a container.

With reference to Figure 1 Off the drawing, the protective cover and container I12 are shown as a unit in assembled relation forming a substantially cylindrical article for economic and efii-cient packaging and storing.

in Figures 2 and 4, the protective cover or cap 10 of my invention is shown associated with a pressure container in the form of a metal can 12 formed at its upper end into a reduced neck portion 14 terminating in a mouth defining bead 16. Pressure containers of this type are conventional and do not form a part of my invention. These containers are of a simple and inexpensive variety and are commonly employed for dispensing liquids, powders and the like by a gas retained under pressure.

My protective cover may be formed of any suitable material such as plastic which may be easily molded into proper shape. I prefer to employ plastics which may be made in a variety of colors and which possess sulficient resiliency to withstand the usualshocks and forces to which an article, suchas the protective cap of my invention may be subjected.

While I have illustrated a particular dispensing valve unit 18 associated with the container 12 it will be understood that any form'of such valve may be employed. In the embodiment herein presented, the valve unit 18 includes an outer connecting or attaching cap or plate 20 having ,an' annular downwardly facing corrugation 22 terminating in a flange or skirt 24 adapted to be seated on and formed into an embraced and crimped relationship with respect to the head 16. l

shown in detail in Figures 2, 4 and 5, the protective cover or cap of my invention comprises a flat circul-ar top portion 26 having a pair of downwardly extending spaced apart, concentric, cylindrical skirts 28 and 30 in which the outer skirt 28 extends a substantial distance 7 and 30 are connected to the top portion 26 forming an integral unit therewith, and are respectively provided with outwardly flaring bevels 32 and 34 at their lower ends. Additionally, the inner skirt is provided with a series of integrally formed lugs 36, 38 and 40 for a purpose presently described.

With particular reference to Figures 2, 3 and 5, the structural relationship of the elements of my protective cover and an associated container may be understood. The outer downwardly directed cylindrical skirt 28 of the cover 10 contacts the container along bevel 32 and forms a continuation of the container body presenting a substantially cylindrical article or package. The innermost cylindrical skirt 30 also contacts the container along the bevel 34 and presents a space 42 for receiving a dispensing valve structure 18..

To maintain the protective cover in position upon the container the interior diameter of the inner skirt 30 is formed to snugly engagethe bead 16 or crimped portion 44 of valve plate 20. Upon applying downward force to the cover 10 with respect to the container 12 the series of lugs 36, 3'8 and 40 on the lower interior edge or surfiace of skirt 30 will ride over and snap behind the bead 16 or crimped portion 44 and assume a position adjacent the body of the container 10.

The cover is formed of a material such as plastic having sufiicient resiliency to securely hold the cover in position on the container until it is desired to use the packaged product. It will be understood that the durable character of the cover permits it to be employed between the periodic intervals of use of the dispenser whereby the valve structure 18 and interior of the cover 10 may be maintained in a clean, sanitary and hygienic condition.

While I have described and illustrated one preferred embodiment of my invention, it will be understood that modification and variation may be made within the scope of the appended claims without departing from the spirit of the invention.

I claim;

1. Ina dispensing package, a cylindrical container having an inwardly and upwardly tapered neck portion terminating in a head, a protective cover for said container comprising a flat circular top portion, an outer cylindrical skirt element extending downwardly from the outer edge of said top portion, said outer skirt element having an outer diameter substantially equal to the outer diameter of said container and an inwardly and upwardly tapered lower edge arranged to engage the outer periphery of said neck portion whereby the covered container presents a substantially smooth cylindrical outer surface extending ubtantially the entire length thereof, and an inner concentric cylindrical skirt element extending down- ;wardly from said top portion a distance substantially less than saidouter skirt element, the lower edge portion of said inner skirt. element. surrounding said bead and hav ing integral lugs extending inwardly thereof tor engaging the outer surface of said bead to detachably secure said cover to'said' container.
